Dicyclopentadiene → Ethylene/propylene 5-ethylidene-2-norbornene dicyclopentadiene

Participants

Reaction Steps

The procedure in Example 1 was substantially repeated except that the feeding rates of 5-ethylidene-2-norbornene and dicyclopentadiene were 1.00 kg/hour and 0.30 kg/hour, respectively, and-the rates of the catalysts dimethylsilyl (2,3,4,5-tetramethylcyclopentadienyl) (3-tert-butyl-5-methyl-2-phenoxy)titanium dichloride, triphenylmethyl tetrakis(pentafluorophenyl)borate and triisobutyl aluminum were 0.057 g/hour, 1.722 g/hour and 3.300 g/hour, respectively. At a polymerization temperature of 83° C., ethylene/propylene/5-ethylidene-2-norbornene/dicyclopentadiene copolymer was produced at a rate of 2.0 kg/hour. Detailed results are shown in Table 1.
